Introduction to Science Concepts

Definition of Science

• Systematic enterprise that builds and organizes knowledge.
• Utilizes empirical methods to study the natural world.

Key Concepts

1. Observation

   • Gathering data through the senses or instruments.

2. Hypothesis

   • Testable statement predicting an outcome based on observations.

3. Experimentation

   • Controlled tests to validate or invalidate hypotheses.

4. Theory

   • Well-substantiated explanation of some aspect of the natural world, based on a body of evidence.

5. Law

   • Statement describing a consistent relationship observed in nature; often expressed mathematically.

Branches of Science

• Natural Sciences

  • Study of the physical universe (e.g., physics, chemistry, biology).

• Social Sciences

  • Study of human behavior and societies (e.g., psychology, sociology, economics).

• Formal Sciences

  • Study of abstract concepts and logical systems (e.g., mathematics, statistics, computer science).

Scientific Method

1. Ask a Question

   • Identify a problem or area of interest.

2. Conduct Background Research

   • Gather existing information related to the question.

3. Formulate a Hypothesis

   • Propose a possible explanation or answer.

4. Test the Hypothesis

   • Design and perform experiments to collect data.

5. Analyze Data and Draw Conclusions

   • Interpret results to determine if they support or refute the hypothesis.

6. Communicate Results

   • Share findings with the scientific community for peer review and further testing.

Importance of Science

• Enhances understanding of the universe.
• Drives technological advancements.
• Informs public policy and health guidelines.
• Promotes critical thinking and problem-solving skills.

Ethics in Science

• Integrity in data collection and reporting.
• Responsibility towards human and environmental welfare.
• Adherence to ethical guidelines in research involving human/animal subjects.

Definition of Science

• Science is a systematic endeavor that builds and organizes knowledge through observation and experimentation.
• Empirical methods are used to investigate and understand the natural world.

Key Concepts

• Observation: Involves collecting data using senses or scientific instruments.
• Hypothesis: A testable prediction about the outcome based on prior observations.
• Experimentation: Conducting controlled tests to confirm or refute the hypothesis.
• Theory: A comprehensive explanation of aspects of the natural world, supported by a substantial body of evidence.
• Law: A concise statement that describes a consistent relationship observed in nature, often represented mathematically.

Branches of Science

• Natural Sciences: Focus on the physical universe (e.g., physics, chemistry, biology).
• Social Sciences: Explore human behavior and societal interactions (e.g., psychology, sociology, economics).
• Formal Sciences: Examine abstract concepts and logical systems (e.g., mathematics, statistics, computer science).

Scientific Method

• Ask a Question: Define a specific problem or area of study.
• Conduct Background Research: Collect existing knowledge related to the question.
• Formulate a Hypothesis: Create a possible explanation or answer to the question.
• Test the Hypothesis: Design and carry out experiments to gather relevant data.
• Analyze Data and Draw Conclusions: Evaluate data results to assess support or contradiction of the hypothesis.
• Communicate Results: Share findings with the scientific community for peer review and validation.

Importance of Science

• Advances understanding of universal principles and phenomena.
• Fuels technological innovations and discoveries.
• Informs and shapes public policy, health standards, and guidelines.
• Encourages the development of critical thinking and effective problem-solving skills.

Ethics in Science

• Emphasizes integrity in gathering and reporting research data.
• Stresses responsibility for the welfare of humans and the environment.
• Requires adherence to ethical principles in studies involving human participants or animals.
